2:273 For the poor, those who are wrapped up in (the) way (of) Allah, not they are able (to) move about in the earth. Think (about) them, the ignorant one, (that they are) self-sufficien (because) of (their) restraint, you recognize them by their mark. Not (do) they ask the people with importunity. And whatever you spend of good, then indeed, Allah of it (is) All-Knower.
